Specification of Letters Patent.

To all 'whom it may concern:

Be it known that I, GEORGE W. ROBERTSON, residing at Marysville, county of York, Province of New Brunswick, Canada, have invented certain new and useful Improvements in Churns; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to chui-ns, the object of my invention is to provide a simple construction by means of which the churn may be locked in a horizontal position for the purpose of lling with a liquid; a further object is to provide in a churn receptacle a removable wall formed from a single piece so that it may be easily cleaned; and, my invention consists of the construe tion, combination and arrangement of parts, as herein illustrated, described and claimed.

In the accompanying drawings, forming part oi this application I have illustrated one form of embodiment of my invention, in which drawings similar reference characters designate corresponding parts, and in which:

Figure l is a side elevation; Fig. 2 'is a plan Fig. 3 is a longitudinal vertical section through the churn receptacle; and, Fig. 4 is a transverse vertical section on line 4 4 of Fig. 3, looking in the direction indicated by the arrow. v

Referring to the drawings: l-l designates base members on which is supported the standards 2 and the braces 3. Disposed on the base members l and the standards 2 are transverse braces 4 to which are secured the hinges 5 carrying the stops 6, the latter of which are adapted to lock the hereinafter described receptacle against movement so that it may be filled, or other churning operations may be carried on when it is not desired that the receptacle should oscillate.

The standards 2 are provided with recesses 7 in their outer ends in which are disposed the pintles 8 carried by the plates 9, secured to the sides Of a substantially rectangular receptacle l0 at approximately the longitudinal centers and adjacent the upper edges thereof, as by means of the screws Il.

The receptacle/l0 is provided with a hinged cover l2 which may be secured by the latch 13. An Open- 45 ing I4 is provided in the upper wall of the receptacle l0, which opening is closed by a glass closure l5, through which the contents of the receptacle can be seen. Handles I6 are provided 0n the end walls of the receptacle by means of which the receptacle may be rocked or lifted from its pivotal support.

One of the end walls ofthe receptacle l0 is provided adjacent its lower end with a docanting opening I7 adapted to be closed by a plug 18, by means oi which opening the liquid contents oi the receptacle IO may be decanted.

The side walls of the receptacle l0 are provided with vertical grooves I9 approximately central of its length adapted to receive a removable partition 20 formed irom a single piece oi material and provided with vertical slots 2l. The object oi making this partition oi a single piece is to provide a construction which may be easily cleaned, and the entire piece being readily rein ovable.

A body of cream 22 is poured into the receptacle l0 through the opening in its upper wall and the receptacle rocked or oscillated on its pivotal support until' the b'utter is formed.

By pivoting the body of the churn adjacent its upper edge, considerably less power is necessary to tilt it from one inclined position to the other. In fact, in practice it has been found that the back wash of the cream is nearly su'flicient to return the receptacle to its first position.

the receptacle I0 is held Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

In a churn, the combination of supporting' nprights, a churn receptacle provided with pntles adjacent the center or' the upper edges of the receptacle, said uprights engaging said pintles, tiansveise braces extending across the lower portions of said uprights and hinged stop members adapted to be seated in operative position on the top edges of said transverse braces i-n engagement with said churn receptacle, said uprights constituting bearings engaging the adjacent sides of said stop .members when the latter are seated in their operative position, whereby all strains exerted on said stop members by the churn receptacle are transmitted directly to said transverse braces and uprights, and the hinges of said stop members maintained free from strain and distortion, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

TH TO JOHN KILBURN,

Patented Aug. 6, 1907.

against movement.
